powered from AC adapters directly. Please contact Microsemi if you require assistance in
selecting the right amplifier for your application.
The antenna mount should be secured to a stable structure such as a building, antenna mast, or
other suitable mounting platform.
H.
The antenna is designed to withstand rain, snow, and dust. When selecting the mounting location
for the antenna, try to find a location that will not become buried in snow and/or covered by
foliage. Keep the top surface of the antenna clean and brush off any ice and snow to ensure that
your antenna performs optimally. In addition, ensure the connector remains clean and dry.
2.4.2 Setting the Antenna Voltage
The 4380A is capable of providing antenna power (0, 5, 12VDC) by DC biasing the antenna cable, but this
can cause damage to an antenna if the wrong voltage is applied. Prior to connecting an antenna to the unit,
ensure the antenna voltage is set properly. The 4380A is shipped from the factory with the default antenna
voltage of 0 volts. If this is not the desired configuration, then follow the steps below to set the proper
antenna voltage.
A.
Telnet into the system command port
telnet ip addr 1700
or connect via the USB Port and the
4380A> prompt should appear.
B.
At the 4380A> prompt, type
settings gps
and press enter, this will display the user configurable
GPS settings for the unit to view and verify the current voltage being supplied to the antenna is
correct.
